. ments in Turbine-Engines', ot which the tch to operate as described inwhich the Huid chamber `is divided, and has a set of nozzles lowing is aspecification.

My invention relates to an improvement 1n turbine engines,` and moreparticnlarlyto Vrotary turbines`to which a constant tiovv ot fluid underpressure from a series nozzles against the vanes on a vane member joursnaled in juxtaposition to the nozzles causes the vane member to berotated and to transmitthis rotary movement to the power shaztt of theengine. i

The' object of thisinvention is toprovide a Huid chamber mounted to bestationary and havinfri lthe nozzles connected. therewith, a rotatablevane member mounted to revolve around the casing, and having a pluralityot series ot vanes on its Working tace and a stationary vane membersecured to the casing With several series of vanes arranged to tit thedifferent scries'ot vanes on the rotatable member. I

A further object is to construct an engine connected with each of thechambers thus formed. The nozzles are positioned to dis charge in theopposite direction and the lvaries on both the stationary and rota-tablevane members are correspondingly reversed. ln this Way the driving andreverse are pro- .vided for.' f

A still further object is to provide a conl trol lfor the supply of Huidto the fluid chamber whereby the fluid may be discharged into either ofthe divisions ot the chamber or entirely cut od'.

With these objects in view' the invention lconsists of certain novelfeatures ot construction'and combinations of parts which 'will ybehereinafter' fully i described and pointed out in the claims.

ln the accompanying dravvings,-l `igure l is a longitudinal verticalsectional View; Fig. @is a view in end elevation with the upper portionsectioned transversely; Fig. Sis a sectional view on the line 33 of Fig.l; Fig. et is a sectional view on the line lil-ll of Fig. 1; Fig. 5 is.af sectional view on the line 5 5, ot Fig'. l; and Fig. 6 is an enlargedfragmentary detail showing the path oi themotive fluid through theseveral series et vanes in dotted lines.

IFhe'engine casing is made in two parts i and. B which are bolted orotherwise secured together, rlhe oil cases C and' D are connected withthe casing members [i and iB and are provided with bearings 1 and 2. Thefluid chamber E is received within the casing members .4t and'B, and asleeve 3 con! nected 'toene of the faces ofthe tliiid cham# ber extendsthrough theA bearing' 2 yWhere it is heldto support the tluid chamberand is secured against rotation by arltev 4.

The iluid chamber'is provided with a central hub 5,;and adividng'vvhe'el t extends.

from this hubto the outer rim 7 of the chain-` ber7 thus forming;virtually tivo duid chambers 8 and QQ The chamber 9, which in thisinstance will be considered as the one designated to give the head'motion to the drive shaft, hasa *plurality oif nozzles l0, 10..` asbetter shown inl Fig. 2, arranged eccentriand one of its faces has twoseries and d.

of detlecting vanes constructed to extend parallel with the central axisot the Huid chamber. 0n the opposite 'tace of the stationary memberGsimilar series of venes f] and e are formed but are arranged to havetheir detiecting' faces on the opposite set trom that or the venes inseries Z) and d.

A rotatable vane member .l is mounted to revolve on the `sleeve and thestub bearing)r 12 ot' the -tluid chamber. This rotatable vane member iscomposed of two castings and 14 Which are bolted or otherwise securedtogether tb in'close and entirely surround the fluid chamber and thestationary vane member G. The casting 13 is mounted to revolve adjacentthe vanes l) ando? on the stationary vane member and has on its inwardtace series of vanes a, c, and e which are positioned vto tit betweenthe series of vanes b and fl lcarried by the member G and are arrangedto have their contact faces po-` sitioned in the reverse direction.Theicast ing le is secured rto `the cashing;l 13 in such `callythrou'ghfthe .rim .7., and the chamber S a manner that it revolves injuxtaposition to the vanes g and z' on the stationary vane member, andprojecting from the inward face are a plurality of vanes which arearranged in series f, 7L, and j so positioned as to fit between theseries of vanes g and z' of the member G. The vanes of the series f, /Land j have their impact positioned in a direction opposite to that ofthe vanes g and z'. The casting 14 has a stub shaft 15 con structedintegral therewith, and a gear 16 is formed on this stub shaft.

Gear wheels 17, as better shown in Fig. 3, are journaled on the casingmember A t0 mesh with the gear wheel 1G. In the present instance l haveshown four of these geax wheels 17, although it is obvious that agreater or lesser number may be used, and also that the size may bevaried to suit the requirements of speed. An internal gear disk 18 isjournaled in the bearing 1 and has the gear teeth 19 thereof meshingwith the teeth of the gear 17. It will thus be seen that when therotatable vane member J is revolved on its bearings, motion istransmitted through the gear 16 to gear 17 and thence to the gear disk18 which is connected to the power shaft Q0 by spline or key 21 in sucha manner that the drive shaft will be rotated.

On the outer end of the sleeve 3 a head 22 is connected and a pipe 23connected therewith leads to the fluid supply. A valve sleeve Q4 isground to fit the internal bores Q5 and 2G of the sleeve 3 and hub 5respectively and -is capable of turing movement in these bores. The hub5 is counterbored at 2T and QS preferably at opposite sides and thecounterbores are so positioned that communication is formed between thebore Q6 and the chamber 9 by the counter-bore 27 and between thel boreQG and the-chamber n by the counter bore Q8. The valve sleeve Q41 iscounterbored at 29 and 30 adjacent the opening to the fluid supply pipe23 and these counterborcs are preferably diametrically opposite. Apassage 31 is formed through the valve sleeve Q4 and positioned toregister with the munterbore Q7 and is preferably located in a lineparallel with thel counter-bore 3() through the sleeve 2i, and a passage3'2 positioned to .register with counterbore 28 is m parallelism withthe counterbore 29. A spindle 33, carried by the valve sleeve Q4,extends -through the outer end of the head Q2 and has rigidly securedthereto a throttle wheel 34, with which the valve sleeve may be turnedupon its axis. An oil well L is formed in the base M on which themembers A and B of the easing are secured, and oil pipes 35 and 3G .leadfrom the oil casings C and D to this oil well. Feed oil pipes 37 and 38are connected with the hub of the casting 13 of the rotatable vanemember J, and have their open ends extending in opposite directions. Thefeed pipe 38 is constructed to supply oil to the bearing on the headmotion and the pipe'?1 on the reverse motion.

In use, it is the intention that the oil casings be lled with oil to adepth as indicated by the dotted lines in Fig. 1, and when this is thecase, the gear disk 18 will sutiiciently agitate and carry the oil inthe casing C to lubricate the bearings on that side and the agitation ofthe oil and the heating in the oil casings will cause the circulationthrough the casings and the oil well, thus keeping the oil at a lowertemperature than would otherwisebe possible and permitting the escape ofsediment from the oil casings.

The operation of the engine is as fol-` lows Assuming that the parts arein the posit-ion shown in Fig. 1, the fluid supply pipe Q3 is closed andalso the passages to the chambers 8 and 9. Now, if it is desired totransmit a head motion to the turbine, the valve sleeve 24 is turned bymeans of the hand wheel 34 to a position that the counterbore Q9registers with the opening from the duid supply pipe 23. This bringspassage 31 in reglster with' counterbere 9.7

and forms an unobstructed line from the fluid supply pipefto thischamber. Theiluid passes out through the nozzles 10 against the vanes inseries a on the rotatable vane member J from which it glances againstthe impact faces. of the vanes in series on the stationary member G fromwhich it is detlected against the vanes in series'c, glances against thevanes in series cl is deflected against the vanes in series e and passesout from the casing through the exhaust opening 10.

The path which the Huid takes through the vanes is better illustrated inFig. 6 and it will of course be understood that'the same travel will beobserved in every instance. vWhen it is desired to again shut off thepower, the parts are returned to the position shown in Fig. 1 and if theoperator desires to reverse the engine, the valve sleeve will be turnedto a position that the counterbore 29 registers with the opening fromthe supply` pipe 23, at which point the passage 32 in the sleeveregisters with counterbore 2S in chamber 8. This leaves an unobstructedpassage to the nozzles 11 which would direct the fluid against the vanesof seriesy f from which it is deflected from the vanes of series g backto series L, then to a' through to and out at the exhaustlopening 40.

ln this way it Will be seen that I have provided an engine in which thefull driving power of the fluid is taken advantage of; also that anengine so constructed will be less bulky than those formerly in use inwhich the two sets of nozzles were arranged in the same circumferentialline around the Wall of the Huid chamber. Further, it will of therotatable lili .ber mounted in juxtaposition to said stanoname cuttingoff the supply of motive Huid to said chambers. l
